The circumference of a circular park is approximately 18 feet. What is the approximate area inside the circular park?
Answers
Answer:
25.685 square feet.
Step-by-step explanation:
Circumference = 2 * π * radius
From this, we can derive the formula for the radius:
radius = Circumference / (2 * π)
Let's substitute the value of the circumference and calculate the approximate radius:
radius = 18 / (2 * π)
radius ≈ 18 / (2 * 3.14159)
radius ≈ 2.865 feet
Now that we have the approximate radius, we can calculate the area:
Area ≈ π * radius²
Area ≈ 3.14159 * (2.865)²
Area ≈ 3.14159 * 8.193225
Area ≈ 25.685 square feet
Therefore, the approximate area inside the circular park is approximately 25.685 square feet.
C = 2πr
where C is the circumference and r is the radius of the circle.
In this case, we are given that the circumference is approximately 18 feet, so we can set up the following equation:
18 = 2πr
Solving for r, we get:
r = 9/π ≈ 2.864 feet
Now we can use the formula for the area of a circle:
A = πr^2
Substituting the value we found for r, we get:
A = π(2.864 ft)^2 ≈ 25.85 ft^2
Therefore, the approximate area inside the circular park is approximately 25.85 square feet.

Interest = Principal x Rate x Time
Plugging in the given values, we get:
Interest = $1,500 x 0.04 x 3 = $180
So Account A earns $180 in interest over three years.
Similarly, we can find the interest earned by Account B using the same formula:
Interest = Principal x Rate x Time
Plugging in the given values, we get:
Interest = $1,500 x 0.06 x (21/12) = $157.50
So Account B earns $157.50 in interest over 21 months.
To compare the interest earned by the two accounts, we can see that Account A earns more interest than Account B, even though the interest rate is lower. This is because the time period is longer for Account A, giving the interest more time to accrue.
Example 1: Two principal amounts and two simple interest rates that would earn equal amounts of interest in one year are:
Principal 1 = $1,000
Rate 1 = 5%
Interest 1 = $50
Principal 2 = $2,000
Rate 2 = 2.5%
Interest 2 = $50
Example 2: Two principal amounts and two periods of time for which the simple interest earned at 2.59% would be equal are:
Principal 1 = $500
Time 1 = 4 years
Interest 1 = $51.80
Principal 2 = $1,000
Time 2 = 2 years
Interest 2 = $51.80

3. The ______ projection shows the size and shape of continents accurately but distorts water areas.
A. Conic
B. Mercator
C. Robinson
D. Interrupted
Answers
The correct answer is A. Conic projection.
A conic projection is a type of map projection created by projecting the surface of a globe onto a cone. The cone is then unrolled and flattened to create a two-dimensional map. Conic projections are best for mapping small areas, such as individual countries or states. They are also good for mapping areas that are located near the equator.
Conic projections show the size and shape of continents accurately, but they distort water areas. This is because the cone is tangent to the globe at one point, and the further away from that point you get, the more distortion there is.
Mercator projection is a cylindrical map projection presented by Flemish geographer and cartographer Gerardus Mercator in 1569. It became the standard map projection for navigation because it is unique in representing north as up and south as down everywhere while preserving local directions and shapes. The map is thereby conformal. As a side effect, the Mercator projection inflates the size of objects away from the equator. This inflation is very small near the equator but accelerates with increasing latitude to become infinite at the poles.
Robinson projection is a map projection presented by American cartographer Arthur H. Robinson in 1963. It is a compromise projection that attempts to balance the distortions of area, shape, and distance. The Robinson projection is neither conformal nor equal-area, but it is pseudocylindrical, which means that the meridians are straight lines and the parallels are circles.
Interrupted projection is a type of map projection that is interrupted at regular intervals. This is done to reduce the distortion of the map. The most common type of interrupted projection is the Mercator projection, which is interrupted at the equator and the prime meridian

Answer: 10x = 4 is x = 0.4.
To solve the equation 10x = 4, we want to isolate the variable x on one side of the equation.
First, we divide both sides of the equation by 10:
10x / 10 = 4 / 10
Simplifying:
x = 0.4
Therefore, the solution to the equation 10x = 4 is x = 0.4.

Step-by-step explanation:
This is defined as a transversal in geometry, where one line intersects two straight lines.
It is given that one of the angles is 42°. Let the angle that measure 42° be denoted as ∠42.
∠4 ≅ ∠42 based on the alternate interior angles theorem.
∠4 ≅ ∠7 based on the vertical angles theorem.
Therefore, ∠42 ≅ ∠7 based on CPCTC.
Therefore,
m∠7 = 42°.
